IMPROVEMENT IN CARDlNG-MACHINES.

Specification forming part of Letters Patent No. 124,351, dated March 5,1872.

To all persons to whom these presents may come Be it known that I,CHARLES JORDAN GOODWIN, of Indian Orchard, of the city of Springfield,of the county of Hampden and State of Massachusetts, have inventedcertain new and useful machinery for carding cotton or other likematerial, and separating from it certain mot-es or matters; and dohereby declare the same to be fully described in the followingspecification and represented in the accompanying drawing, which denotesa vertical section of parts of a cotton-carding engine, with my additionor additions thereto, the object of such addition or additions being todischarge from the carding-engine and collect in a mass certain motes ormatters, which, enter ing the machine with the fibrous material, wouldotherwise be found in the latter when carded.

Heretofore, theprocess of cleaning cotton has been imperfect, and, in myopinion, conducted on false principles, as will appear fromconsideration of the nature of the matters necessary to be removed. Theyconsist of small bits or pieces of the boll and of the leaf of thecotton-plant, they being held among the fibers of the cotton, but notabsolutely attached thereto. There are other matters in cotton, termednits, which areattached to the fiber, and are a sign or evidence ofimperfect formation of it. My additions to the carding-engine are forthe purpose of removing motes or extraneous matters from cotton or otherfibrous material preparatory to its passage between the top flats andmain card-cylinder of such engine. These motes or extraneous matters notbeing attached firmly to the fibers are removable therefrom. Theprocesses heretofore adopted to effect their removal have been byopening and picking the cotton by machinery furnished with heaters, andsieves, and other equivalent devices, the intention being to shake orbeat out the motes; but, owing to circumstances, all such modes ofprocedure have not had the desired effects, and it is still adesideratum to find some better or perfect mechanism to accomplish theend desired with the least injury to the staple. With most if not allthe methods heretofore used to cleanse the cotton of its impurities, aconsiderable amount of the motes have remained 111 the bat,

and at its front by the card-cylinder.

and, as a consequence, have passed into the slivers and been twistedinto the yarn, and subsequently woven into the cloth, to its detriment.My invention effects very thoroughly the interceptin g of the saidforeign substances as they are discharged from the cotton, just abovethe feed-rollers of the carding-engine. By thus intercepting the saidmotes or matters, they are prevented from being caught between the maincard-cylinder and the top flats and again mingled with the cotton. Inmost if not all carding-engines there is aspace between the feedrollsand the lower of the top flats, such space at its rear being bounded bythe front board, The rapid rotation of the card-cylinder produces ablast of air that separates the motes from the fibers of cotton whilepassing from the feed-rollers to the cylinder. They leaving the cylindertangentially,.as they are allowed to do, are assisted by this blast, andconveyed quickly into the receptacle. It has been found that most of themotes are here substantially separated from the fiber, since, if thefront board or boards be removed, a current of motes will be seen thrownoff and passing over the feed-rollers, and falling upon the lap orcotton outside.

The nature of my invention may be said to consist as follows: First, ina dirt-receptacle having a rigid lip, when arranged over thefeed-rollers and with relation to the teeth of the main card-cylinder tooperate as and and for the purpose described. Second, in the combinationof a deflector with the feed-rollers dirt-receptacle, with its lip andcard-cylinder arranged as described, the deflector being below the topflats, and serving to intercept the motes and deflect them into thereceptacle, and thereby prevent them from falling upon the lap or beingthrown upon the cotton or fibrous material held by the maincard-cylinder.

The drawing shows the main operative parts of a carding-engine, withwhich my additions are combined and coact; A being the maincard-cylinder, B B the series of top flats, O the delivery-apron roller,and D l) the feedrolls. E is the front board, made in two parts, a b,hinged together. F is the receiver, trough or box, arranged immediatelyover the feed-rollers and open at top It may be applied to the frame ofthe engine so as to be capable of beingremoved therefrom and securedthereto, as circumstances may require. Above this receptacle is thedeflector G, which projects from and extends horizontally along thefront board on its inner surface, and between the receiver F and thefirst or lowermost top flat.

In the operation of the machine, the motes discharged from the cotton bythe main card.- cylinder while the cotton may be in the act of beingdelivered by the feed-rollers will be thrown upward against thedeflector, and by it will be deflected into the box or reservoir, fromwhich they may be removed as occasion nay require. Thus they will beprevented from being thrown upon the cotton, so as to be carried betweenthe cylinder and the top flats. The mote-receptacle has a rigid l p orside, (3, arranged above the feed-rollers, and but a shortdistance fromthe teeth of the cardcylinder, such lip serving to cause the cotton tobe well embedded into the spaces between the teeth of the cylinder, sothat the longer fibers will not leave the cylinder opposite thedirt-receptacle. The motes and line fly leave the cylinder tangentiallyopposite the receptacle. The motes being heavy are stopped by thedeflector and allowed to drop into the receptacle, the fine fly, whichis very light, being by the deflector retained until seized and drawnaway by the teeth of the cylinder. \Vhere the lower top flat has itsedge projecting inward beyond the front board so as to serve as adeflector, it will frequently happen that no other deflector need beused with the receiver, in which case the ieceiver would have to be themain addition to the carding-engine to efi'ect the purpose desired.

I arrange the dirt-receptacle directly over the teed-rollers, and withits inner side parallel, or about so, with and near to the teeth of themain card-cylinder; such being to cause the dirt-box, besides serving tocatch the motes, to perform another function, as hereinbefore mentioned.My arrangement enables me to dispense with any movable flap to thedirt-box, such flap being an in'lpediment to the correct operation ofthe machine, as being mo able it is liable to be thrown up by the cottonwhich may accumulate underneath it, in which case the mass accumulatedwill be drawn away by the card-cylinder, whereby an uneven sliver isliable to be made.

I make no claim, broadly, to a i'note-receptacle in combination withteed-rollers, as such a combination is shown in patent 103,889.

I claim- 1. The dirt-receptacle having the rigid lip, when arranged overthe feed-rollers, and with relation to the teeth of the card-cylinder,to operate as and for the purpose described.

2. Also, the combination of the deflector with the teed-rollers,dirt-receptacle with its lip, and card-cylinder, when arranged as abovedescribed.
